If you are a beginner in wireless you will hear those who are experienced speak of a telephone receiver as having a resistance of 75 ohms, 1,000 ohms, 2,000 or 3,000 ohms, as the case may be; from this you will gather that the higher the resistance of the wire on the magnets the more sensitive the receiver is.
Their tombs have stood for two centuries, as mighty magnets drawing others to self-impalement on the sword as multipliers of suicides. Yet this alphabetic number, this i-ro-ha of self-murder, is but one of a thousand instances in the Land of Noble Suicides.
Stewart speaks as follows: "I made an exhibition of the 'Jumbo' in the theatre at Santiago, and on the first evening, when it was filled with the aristocracy of the city, I discovered to my horror that the binding wire around the armature was slowly stripping off and going to pieces. We had no means of boring out the field magnets, and we cut grooves in them.
As our fears, like our wishes, when strong and unremitting, prove to be magnets, the result of Joy's despondent fears came in the scandal which the Baroness had planted and left to flourish and grow in Beryngford after her departure. An hour before the services began, on the day of Preston Cheney's burial, Joy learned at whose rites she was to officiate as organist.
Hilaire have a lot of power and they will use it for you." Harry was walking on the hills that look down on the Capitol, when he read the letter and its warm words made his pulses leap with pleasure. He felt now the pull of opposing magnets.
When next I saw Kennedy it was late in the afternoon, in the laboratory. He was arranging something in the top drawer of a flat-top desk. It seemed to be two instruments composed of many levers and discs and magnets, each instrument with a roll of paper about five inches wide. On one was a sort of stylus with two silk cords attached at right angles to each other near the point.
He could see only a sunny head fairly rioting with curls; a pair of eyes that held his like magnets, although they never gave him a glance of love; a smile that lighted the world far better than the sun; a dimple into which his heart fell headlong whenever he looked at it!
We can cut off the power from any single motor by the mere break of contact between two pieces of metal; we can restore the power by merely letting the two pieces of metal touch; we can make these changes by electro magnets with the rapidity of thought, and we can deal as we please with each of one hundred motors without sensibly affecting the others.
The art, if indeed there can be said to have been an art at that time, was in chaotic confusion, and only because of Edison's many years' study of the magnet was he enabled to conclude that insufficiency in quantity of iron in the magnets of such machines, together with poor surface contacts, rendered the cost of magnetization abnormally high.
They must be patient and long-suffering, that they may grow to become the divine magnets of the Abhá Kingdom and acquire the dynamic power of the hosts of the realm on high.
